The reason for asking about mixed mode authentication is that if you can connect using a connectionstring like this;
Server=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;
but not like this;
Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;
then you do have a permissions issue. However, most connection problems are due to incorrectly naming the server or database. The more things we can discount, the easier it will be to fix.

This is almost a non-issue, as I have halfway decided to use SqlLite instead. Thanks anyway.

Could someone help me with this one perhaps?
Let's say I have a simple SQL query like:
SELECT EmployeeID, EmployeeName, YearStarted FROM Employees
I'd like to return a fourth column in the result set of which the value is conditional upon the value of another column. For instance, if the value of YearStarted is older than 2007, return 'veteran' otherwise return 'spring chicken'.
I'm thining something like:
SELECT EmployeeID, EmployeeName, YearStarted, IF(YearStarted<2007,'Veteran','Spring Chicken') FROM Employees
but obviously such an IF statement doesn't exist in SQL. Is there another way to do it?
|
|
|
|
|
select
EmployeeID,
EmployeeName,
YearStarted,
case
when YearStarted < 2007 then 'Veteran'
else 'Spring Chicken'
end NewColumn
from
Employees

yeah i forgot to say sql 2008!
but what i meant was which edition? standard? enterprise? ....?

The OS has very little relevance of the edition you should use, it depends on your database requirements, This may help http://www.microsoft.com/sqlserver/2008/en/us/editions.aspx[^]
If you are asking about a development environment then use either developer or express versions.

For many years I have been using vb6 with Access Database as back end. In many cases while returning record sets Access is omitting the very first record and it returns the rest of the records. I am really baffled. Please help.
Hi all of you, I have corrected my mistake and got the answer for this question.
Here is how I got it solved. The records were stored with time field. When querying up I did not mention the begining of the starting day (like 00:01 - which implies the start time of the day) and the end of the day in the finishing date. (Thought up this solution very late.) And so I was getting a few records eliminated from the query result set.
Thanks for all of you who tried to help and you can consider my question closed.
Hope this helps somebody.

Are you confusing zero-based and one-based indexing for arrays?
Otherwise, showing some code might help us help you.

Whatever it returns first is the first. Or maybe you're using it wrong.

Dear,
Can anyone help me to make good database structure?
What i have are some locations where I have some machines. Every machines have 2 counters (IN and OUT). I need to be able to enter state of that counters and after that to compare that values with previous entry IN and OUT counters.
How I see it seams that somewere I need to keep information wich machine is on wich location. Beside that I need to track information about date and time of entries.
Situation:
Location 1 -> machine1, machine2, machine3
Location 2 -> machine4
Location 3 -> machine5, machine6, machine7, machine8
....
I need 3 kind of reports:
○ Deference between new IN / OUT and some old IN/OUT counters for every machine
○ Total IN/OUT for some location
○ Total IN/OUT for all location
How I need to organize this datas?
Thanks for helping me,

3 tables
Location
LocationID int identity(1,1)
Location varchar(20)
Machine
MachineID int identity (1,1)
LocationID int
Machine varchar(20)
TranTable
TranID identity (1,1)
MachineID
Direction
Date
This assumes a machine can have only 1 location and the machine can be checked in/out many times. Using a date on the transaction table will allow you to get durations, and state on a given date

Hi All,
I am using SQL Server 2005. My problem is that I am unable to start MSSQL Server. When I go to services.msc, i found that the state of MSSQLServer is stopped. When I click on start, it gives me this error:
The SQL Server (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts Service.
I try all possible things, google it and atlast re-install SQL Server but nothing happen. So please help me??
Thanks

Yikes - wish I hadn't asked.
Okay, well, I'd be looking for the first reported error and concentrate on that:
Starting up database 'master'.<br />
Error: 17207, Severity: 16, State: 1.
Start with that and see how far you get. (If anyone else has a better suggestion now would be the time...)

Hello,
let's have the following simple example. An SQL table consists of three columns:
RecordId,
GenerationId,
Fitness.
RecordId is a unique key. GenerationId and Fitness columns contain values that might and do repeat themselves over many rows.
Now how to do a simple select of the unique RecordId which has the highest Fitness, grouped by GenerationId?
Obviously,
SELECT max(Fitness) FROM myTable GROUP BY GenerationId
returns the highest Fitness for each GenerationId, but how to get the particular row which has this highest Fitness?
Fitness values might repeat themselves for the same GenerationId values, so an aggregate function also has to be used to select a distinct RecordId for a particular GenerationId. It doesn't matter which RecordId is selected as long as it has the highest Fitness for the particular GenerationId.
Thank you very much for any ideas!
Michal

the result should look something like this:
GenerationId, Fitness, RecordId
0,312.53,12
1,365.42,18
2,412.56,28
3,418.26,34
4,526.79,41
5,528.,48
...
|
|
|
|
|
Do you have some sample data for the table that would be used to get the result you're looking for?
Scott
|
|
|
|

yes, let's use the following sample data.
source table:
RecordId GenerationId Fitness
0 0 150.5
1 0 148.2
2 0 172.5
3 1 183.2
4 1 189.8
5 1 183.2
6 1 215.1
7 1 221.3
8 2 208.4
9 2 232.1
10 3 225.1
11 3 236.4
12 3 231.5
13 3 236.4
14 4 236.4
15 4 245.1
16 5 251.9
17 5 250.4
18 6 251.9
19 6 262.4
based on how one aggregates multiple rows with the same Fitness for the same GenerationId, one of the possible outcomes should look like the following. here I used max(RecordId), but it doesn't really matter:
GenerationId maxFitness RecordId
0 172.5 2
1 221.3 7
2 232.1 9
3 236.4 13
4 245.1 15
5 251.9 16
6 262.4 19
I'm able to achieve this result with joining the source table to itself, but I hope there has to be a more elegant way on how to do this without breaking one's neck with multiple lines of SQL code.
thanks for any help and ideas!
